Application filed November 22, 1909. Serial No. 522,174.

To aZZ whom it may concern:

Be it known that I, WILLIAM n'r'rin, a citizen of the United States, residing at orcester, in the county of Worcester and State of Massachusetts, have invented certain new and useful Improvements in Pile ires for Pile-Fabric Looms, of which the following 18 a specification.

My invention relates to a pile wire for pile fabric looms, and to that class of pile.

fabric looms in which stationary wires are used, over which the pile loops are formed,

and whichextend in the direction of the length of the warps. a

My invention particularly relates to an improved construction of the pile wire over which the pile loops areformed, and the upright wire or support which carries the pile wire proper, and more particularly the mannerof attaching the pile wire,"whieh is made separate from its support, to said support.

The object of my invention is to improve upon the construction of the pile wires of the type shown and described in U. S. Let ters Patent, No. 790,017. I

In my improved construction of a pile wire, the pile wire proper, and its support, are made separate from each other, and are rigidly attached together. The upper end of the pile wire support is preferably bent over to form an oblong loop, and the attached end of the pile wire proper is bent or made of angle shape, and extends into said loop, and is rigidly attached thereto by solder, brazing, or welding.

I have shown in the drawing a single improved pile wire embodying my improvements, and a guide strip combined therewith.

Referring to the drawing :Figure 1 is a side view of a pile wire, and its supporting wire, and a guide strip, embodying my improvements, looking in the direction of arrow a, Fig. 2, and showing in section the supporting bars. Fig. 2 is an edge view of the parts shown in Fig. 1, looking in the direction of arrow 6, same figure; the sup porting bars are not shown in this figure. Fig. 3 is, on an enlarged scale, a section through the inner end of the pile wire, and the upper end of the supporting wire, on line 3, 3, Fig. 1, looking in the direction of arrow 5, same figure, and, Fig. 4 shows, on an enlarged scale, the inner end of the pile wire, detached In the accompanying drawing, 1 is the pile wire, preferably made of fiat metal, and of substantially the shape shown, having the straight end 1 extending in a substantially horizontal plane, over which the'pile loops are formed in the usual and well known way, and the'upwardly inclined rear portion 1".

2 is the upright wire or support for the pile wire 1, preferably made of flat metal, and separate from the pile wire 1. The lower end of said upright wire 2 is preferably notched at 2, as shown in Fig. 1, to receive a pro]ection 3 on a transverse bar 3, which is secured by a bolt 4 to the transverse bar 5-, to hold the upright wires or supports 2 in position. The upper end of the upright wire or support 2 is bent over to form a loop 2", see Fig. 3, and the free end of the loop is preferably soldered or brazed, or welded to the main part of the wire or sup port 2. lVithin the loop 2", on the upper end of the wire 2, extends the angle shaped end 1 on the pile wire 1. The angle shaped end 1 is rigidly secured within the loop on the uprightwire or support 2, by soldering or brazing. By forming the looped upper end of the upright wire or support 2, by bending over the upper end of said wire, a thin strip of metal, of substantially uniform thickness, may be used for the upright wires 2, and the boring or making of a hole through the upper end of the wire for the reception of the end of the pile wire. to be secured therein, is avoided; the

bending of the wire produces a substantially this construction of the upright wire or blade, the cost of the upright wires 2 is con siderably reduced. The upright wire 2 has in this instance an offset 2 at its upper end, and has secured to its lower part the lower end of the guide strip 6, in this instance by having the lower edges of said guide strip bent around the upright wire 2, and soldered or otherwise secured thereto. The guide strip 6 is preferably made of thin flat metal and extends upwardly above the upper end of the upright wire or support 2, and is slightly inclined rearwardly, and acts to retain the pile warps in their proper relative position, and to guide them when they are raised over the top of the upright wire or support 2, in the usual and well known way.

T e ad ant ges of my i pro ements in pile wire will be readily appreciated bythose skilled in the art. I provide a pile wire for the pile loops, which is made separate from the supporting wire or blade, and is rigidlynttached to the upper end of said supporting wire in such a manner that the point of attachment forms a smooth and even surface which does not interfere in any way with the passage of the pile warp on either side of the upper end of the supporting wire. The soldering or brazing, or welding of the attached end of the pile wire within the loop at the upper end of the supporting wire, makes a smooth and secure joint, the two parts being substantially integral. The upper end of the looped end of the supporting wire may be pointed or wedge-shape to form an unobstructed and smooth surface for the pile warp to pass down on either side thereof. The thinness of the upper end of the supporting wire and the attached end of the pile wire, al lows a larger number of pile wires to be used in the same space, and gives more space between the individual pile wires for the pile warps, in case a less number of pile wires are used.

It will. be understood that the details of construction of my improvements'may be varied if desired.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent is:

1. The combination with a pile wire over which the pile loops are formed, and an upright blade made separate therefrom, and having its lower end notched on one edge to receive a projection on a transverse bar to secure said upright blade in position, and

having at its upper end a loop formed by bending over the end of said upright blade, said loop of wedge'shape at its upper end, and having the attached end of the pile wire rigidly secured therein, of a guide strip having its upper end free and extending above the attached end of the pile wire, and its lower endsecured to the lower part '01 said upright blade.

2. The combination with a pile wire over which the pile loops are formed, and an upright blade made separate therefrom, and having a loop at its upper end formed by bending over the end of said upright blade, said loop of wedgeshape at its upper end, and having the attached end of the pile wire rigidly secured therein, of a guide strip, having its upright end extending above the attached end of the pile wire, and its lower end secured to the lower part of said upright blade.

3. The combination with a pile wire over which the pile loops are formed, and an upright blade made separate therefrom, and having an ofiset therein, and having a loop at its upper end formed by bending over the end of said upright blade, said loop of wedge shape at its upper end, and having the attached end of the pile wire rigidly secured therein, of a guide strip, having its upright end extending above the attached end of the pile wire, and its lower end secured to the lower part of said upright blade by bending over the edges thereof on said blade.
